The 0xe2 byte thing sounds like a non-ASCII character sneaked into in the
file with the code. In your email the transposition sign after the ] looks
suspicious, but after sending via email anything can happen.
Ah, that's it: the transposition symbol in gretl is 0x27 (the ASCII
plain, upright single quote), but in Paolo's mail that's replaced with
"right single quotation mark" (character 0x92 in Windows code page
1252). On conversion to UTF-8 that becomes the 3-byte sequence 0xE2
0x80 0x99, which begins with 0xE2!
